PHYS 340, Electricity and Magnetism. I had to either take this courseor Thermodynamics and Statistical Physics. I hate both electromagnetism and thermodynamics so I took the one I had a chance of understanding.

EDIT: Oh crap, I just remembered I had done both courses. McGill made me miserable at times.

God I hate those 2 classes. At least thermo isn't as bad but my teacher can be a dick at times.
